GNU GRUB on MBR-partitioned hard disk drives

GNU GRUB on GPT-partitioned hard disk drives

boot.img has the exact size of 446 Bytes and is written to the MBR (sector 0). core.img is written to the empty sectors between the MBR and the first partition, if available (for legacy reasons the first partition starts at sector 63 instead of sector 1, but this is not mandatory). The /boot/grub-directory can be located on an distinct partition, or on the /-partition.

GRUB har i dei fleste Linuxdistribusjonar tatt over rolla som standard operativsystemslastar for forgjengaren LILO.
